in volume by the closing of the canal, thereby 

 making the transportation of aspens upstream 

 less laborious. 



When the downstream aspens at last reposed 

 in a pile beside the house, harvesting was briskly 

 begun in the aspens along the shore of the new 

 pond. Then came another surprise. The bow 

 dam was repaired, and the canal not only opened, 

 but enlarged so that almost all the water in the 

 brook was diverted into the canal, through which 

 it flowed into the new pond. 



The aspens cut on the shore of the new pond 

 were floated across it, then dragged up the canal 

 into the old pond. Evidently the beavers not only 

 had again turned the water into the canal that 

 they might use it in transportation, but also had 

 increased the original volume of water simply to 

 make this transportation of the aspens as easy as 

 possible. 



Their new works enabled the colonists to pro- 

 cure nearly five hundred aspens for the winter. 

 All these were taken up the new canal, dragged 

 over the bow and the main dams, and piled in 

 the water by the house. In addition to these, the
